MACHINE FOR SPLlTTlNG THE TANGS AND SI -IAPING THE BODIES OFSHOVEL-BLANKS.

SFECIPICA TI ON forming part of Letters Patent No. 367,834-, dated August 9, 1887.

Application filed March 21,1981.

Serial No. 231.740. (No model.)

To all whom, it 77mg concern.-

it known thatI, HENRY MILTON MYERs, a c1t1zen of the United States, residing at Beaver Falls, in the county of Beaver and State of machine shown in my Patent No. 348,037,

dated August 24, 1886.

The invention will be hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings,which form apart of this specification, Figure 1 represents a front elevation of my improved machine; Fig. 2, a side elevation. Fig. 3 is a plan view of the saddle. Figs. 4 and 5 are vertical sections of a modified construction. Figs. 6 and 7 are'detail views of a blank and dies to be inserted in the saddle.

Reference being hadto the drawings and the letters marked thereon, A represents an ordinary punchingnnachine having what is known as a stop-motion, and in which machine is inserted a splittingknife or cutter, B. 0 represents a saddle detachably secured to the machine by bolts a, and between the side walls, I) c, is formeda groove in which blocks or cheekpieces d e and .rollers f g operate to clamp the tang-supporting jaws h iagainst the blank D, The upper ends of thejaws h t are cut away, as shown at 1 2, to form supports for the arms 3 4 of the tang when rolled out to form the handle-straps of the shovel. The

jaws are attached to the reciprocating head by rightangled hooks 5 6, and project down through the saddle into the base of the machine. i

On each side of the head is attached alever, 7c, which is pivotally connected to links I Z, forming a toggle-lever. The opposite ends of the links H are connected to the rollers f gby a pin or bolt passing through them, and the rollers are conncted to the blocks d e-by straps or links an for drawing the blocks away from the jaws h i to'rclease the blank D after the tang has been split.

Upon the saddle (l is formed an anvil, 0, and upon the head of the machine is a hammer, p, for closing the arms 3 4 ofa split tang.

E F, in, Figs. 6 and 7, represent anvils, the former having a concave upper surface, 1', and the latter a convex surface, s. The anvils are inserted in the saddle G for the blank D to rest upon while being split and to impart to the lower edge, t, of the blank a convex or a concave surface, according to the kind of shovels being made, whether square or round points orends. I do not, however, limit myself to this particular means for sharpening the blank, as it may be cut into the form shown in the drawings, or it may be thus formed in dies'before it is inserted in the splitting-machine.

/ I11 the manufacture of shovels it is well known that in rolling a blade longitudinally the end of the blade forms a semicircular or an irregularline. Thereforeto provide against such a formation in the one and to increase the rounded point in the other the blank is formed as shown, either convex, as in Fig.6, for roundpoint shovels, or concave, as in Fig. 7, for square-point shovels. The anvils are interchangeable, and can be easily and readily adjusted upon the saddle;

In another application filed herewith, Serial No. 231,741, the blank having a concave or convex lower end is claimed as a new article of manufacture. In Figs. 4 and 5 are shown a modification, and in which the tang-supporting jaws h z are beveled in the reverse direction attheir opposite ends. The lower ends, 7 8, work upon correspondiugly-beveled blocks 9 10 in the base of the machine, and the upper ends, 11 12, engage with correspondinglybeveled ends of pieces 13 I l, which are secured to thehead of the machine. The jaws h i are also secured to the pieces 13 14 by bolts 15, which work in elongated slots 16 in said pieces 13 14. The jaws 7t 2' in both constructions reciprocate with the head and clamp'the blank D while the tang is being split, and at the same time the upper or cut-away portions, 1 2, of the jaws support the arms 3 4 of the tang.

ICC

By the jaws moving with the head and the arms 3 4 being supported laterally the knife 13 advances into the tang evenly and prevents its running off to one side. The knife is forced down a sufficient distance to form the socket in the body of the blank for the reception of the tapered end of a wooden handle.

In the construction shown in Figs. 1 and 2 the reciprocating head operates the togglelevers, and in its descent forces the rollers f g and the blocks d 0 against the jaws h 17, which clamp the blank D and support the arms 3 4 of the tang. The upward movement of the head draws the toggle-lever toward the machine and blocks (Z c away from the jaws 71. i, which releases the blank D. The blank is then removed by the operator, and a little cinder thrown into the socket and between the split tang, after which the tang is placed upon the anvil 0, when it is struck by the hammer p, and the arms 3 4 closed. The blank is then passed onto the rolls employed for reducing it to the shearing-point.

Having thus fully described my invention, what I claim is- 1. In a machine for splitting shovel-blanks, a reciprocating head provided with a cutter, in combination with tang-supporting jaws conneeted to the head and moved synchronously therewith, substantially as described.

2. In a machine for splitting shovel-blanks, a reciprocating head provided with a cutter, in combination with tang-supporting blankclamping jaws connected to and reciprocating with the head and moved laterally to clamp the blank by mechanism connected to the head, substantially as described.

3. In a machine for splitting shovel-blanks, a reciprocating head provided with a cutter, in combination with tang-supporting blankclamping jaws connected to the head, and a toggle-lever attached to the head and operating to move the jaws laterally to clamp the blank, substantially as described.

4. In a machine for splitting shovel-blanks, a reciprocating head provided with a cutter, in combination with tang-supporting blankclamping jaws connected to the head, levers connected to the sides of the head and carrying rollers at the opposite ends, and movable blocks operated by the levers to move the jaws laterally, substantially as described.

5. In a machine for splitting shovel-blanks, an anvil for forming concave or convex surfaces on the blank while the tang thereof is being split and the socket formed, substantially as described.

6. The combination of a reciprocating head, an anvil having a concave or a convex upper surface, and clamping devices for holding a shovel-blank, substantially as described.

In testimony whereof I affix mysignature in presence of two witnesses.

HENRY MILTON MYERS.
